DIFFERENTIAL MECHANISM.

Application filed February 4, 1921.

To all 1li/mm. 'it /nf/l/ Concern.'

Be it known that I, FRANCIS il. Roo'r, a citizen of the United States, and a resident of `Watertown`r in the county of .lajtierson 5 and State of New Yorkn have invented a eer-- tain new and useful Differential Mechanism, ot which the following is a specification.

This invention has for its object a differcntial mechanism or gearing which is particularly simple in construction. economical in manufacture and highly ctlicient and durable in use.

The invention consists in the novel features and in the combinations and construetions hereinafter set t'orth and claimed.

ln describing this invention`r reference is had to the accompanying drawings. in which like characters designate corresponding parts in all the views.

Figure l is a side elevation, partly in seetion, of my di tl'erential gear and contiguous parts; and

Figure Q is a sertional view, taken on linel :2m-2, Figure l.

This ditl'erential gearing comprises generally. opposing main heels or gears, a driving element. and an endless rarmvfrv rarried hy the driving element and inr'luding side portions having slots {o r rereiving the 30 working faces ot' said wheels or gearsl and end portions extending transversely of the driving wheel and eonneeting side portions and parts movable through the raoeway and eoaeting with the opposing wheels or gears :i5 to transmit the differential motion oi either to the other.

l designates the main, or side gears, which are mountable upon shaft sei-tions 2 in any nell-known manner.

These side wheels are formed with sockets 3.

4 designates the driving element, which may he carried by a casing or formed as a part oi' the easing in the ordinary manner.

5 is a raeeway carried by' the driving cle- A'10 here shown as Serial Ne. 442510,

nient over which the compensating mechanism passes, the raeeway having side portions G arranged in juxtaposition to the soeleted portions ot the wheels l and heing here shown as formed with slots T for receiving the socletcd portions or peripheries of the wheels L and end portions extending transw'ersel)7 oi the driving element and Connecting the side portions so that the rat-ewa),v is endless.

fl are halls movzhle through the raemvay and adapted to he received in the sovkets ot the wheels. so that when there is any differential movement between the two shat't sections, such differential movement is transmitted from one wheel i to the other hy the passing ot' the halls through the raeeway.

ln the present embodiment of my invention two raeeways are shown arranged on di ammetrieally opposite sides of the shaft 2.

The driving element 4 may loe actuated in any suitable manner as hy a chain, driving sh att with gears ete.N hut it is here shown as actuated hy a power transmitting mechanism Yforming the snlrieet-niatter of another application.

what l rlaim ist` differential nierhanisni roniprising a driving elementw a raeewav carried hy the driving element and including side portions extending on opposite sides ol' the driving element and end portions eonnerting the side portions, the side portions ol the raceway heing open at their outer lateral sides, halls movahle in the raeeway. and opposing wheels having soci-iets extending lhroigh the open sides ot' the raeewaj.' l'or receiving the halls, substantially as and tor the purpose described.

In testimony whereof, I have hereunto signed my name, at lilatertown, in thel County ot Jefferson, and State of New York, this 4t day of Jan., i921.

FRANCIS H. ROOT.
